JavaScript => public var bounds: Bounds;
C# => public Bounds bounds;

Description 描述

The bounding volume of the mesh.

网格的边界体。

This is the axis-aligned bounding box of the mesh in its local space (that is, not affected by the transform). Note that the Renderer.bounds property is similar but returns the bounds in world space.

在网格局部坐标空间，轴对齐的边界盒 （不会受到变换的影响）。注意，与Renderer.bounds属性相识，但返回的是世界坐标空间的边界盒。

JavaScript:

	// Generates planar UV coordinates independent of mesh size
	// by scaling vertices by the bounding box size
 
	function Start () {
		var mesh : Mesh = GetComponent.<MeshFilter>().mesh;
		var vertices : Vector3[] = mesh.vertices;
		var uvs : Vector2[]  = new Vector2[vertices.Length];
		var bounds : Bounds = mesh.bounds;
 
		for (var i = 0; i < uvs.Length; i++)
			uvs[i] = Vector2 (vertices[i].x / bounds.size.x
							 ,vertices[i].z / bounds.size.x);
 
		mesh.uv = uvs;
	}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    void Start() {
        Mesh mesh = GetComponent<MeshFilter>().mesh;
        Vector3[] vertices = mesh.vertices;
        Vector2[] uvs = new Vector2[vertices.Length];
        Bounds bounds = mesh.bounds;
        int i = 0;
        while (i < uvs.Length) {
            uvs[i] = new Vector2(vertices[i].x / bounds.size.x, vertices[i].z / bounds.size.x);
            i++;
        }
        mesh.uv = uvs;
    }
}
